The blue resistances are contained within the µModule
device, and the green are outside.
The die temperature of the LTM8062/LTM8062A must be
lower than the maximum rating of 125°C, so care should
be taken in the layout of the circuit to ensure good heat
sinking of the LTM8062/LTM8062A. The bulk of the heat
flow out of the LTM8062/LTM8062A is through the bottom
of the module and the LGA pads into the printed circuit
board. Consequently a poor printed circuit board design
can cause excessive heating, resulting in impaired perfor-
mance or reliability. Please refer to the PCB Layout section
for printed circuit board design suggestions.
